Title: Improvements in and relating to centrifugal separators
IPC: B04B11/08
Filed: 1929-10-11
Abstract: 333,452. Molen, E. van der. Oct. 11, 1929. Strainer separators; charging and discharging. -In a centrifugal separator the feed of the rotor and the discharge thereof progress axially and in the same direction; the operating means ensure that the actions occur in proper sequence. The suspended rotor 3 has a perforated wall, and is divided into compartments a - - e by horizontal annular partitions 7. These compartments are fed with the substance for treatment by pipes which can be successively connected to the supply pipe 23 by a multi-way cock 24 operated by ratchet mechanism from a collar 28 which can slide but not rotate on the sleeve 10. The scraper 11 is attached to the sleeve 10 which is mounted on a fixed spindle 9 and the scraper movements are obtained by the engagement of the roller 20 on a lever 21 attached to the sleeve 10, with a cam 19 secured to a spindle which also carries the cylinder 17 driven through worm gearing 18. The control cylinder 17 has a cam groove 16 in windings corresponding to the compartments in the separator rotor. Each winding extends horizontally for three-quarters of the circumference of the cylinder, and during the remaining quarter it slopes to join the next winding. An arm 14 on the sleeve 10 projects into the groove 16 and gives the necessary axial motion to the sleeve. The scraper 11 is operated in the lowest compartment, is then moved in towards the axis of the rotor and lifted clear of the partition 7. It is then swung outwards to clear the next compartment and at the same time the ratchet mechanism operates the cock 24 to connect the supply pipe 23 to the feed pipe for the lowest compactment. This succession is repeated and after the scraper has cleared the top compartment it is returned to the lowest compartment In the modification shown in Fig. 3 the walls of each compartment are imperforate, but sections i of perforate walls are arranged between the compartments. Flexible scrapers or air jets may be used, and only one feed pipe may be used and connected to supply each compartment in turn.

Title: Hot-rolling of metal slabs
IPC: B21B39/16
Filed: 1970-06-29
Abstract: 1311566 Rolling mills HOESCH AG 29 June 1970 [5 July 1969] 31341/70 Heading B3M A metal slab is rolled into strip in a mill having a roughing train (or a reversing stand) and a finishing train, the strip being subject to interstand tension in the finishing train and to interstand compression when being rolled from the slab. An intermediate rolling train can be combined with the finishing train. The arrangement of the mill is designed to reduce the heat loss from the work during rolling. In order to control the width of the strip, assemblies 12, Fig. 8, are located between the stands of the roughing train, the stands having edging rolls associated with them. Each assembly 12 includes a roller 804 over which the strip passes, and an upper cylinder 121 which creates a compressive force on the strip. The speed of the rolls in the second stand 102 is initially adjusted so that the volume of material passing through the stand 102 is less than that supplied to the previous stand 101. A temporary build-up of material occurs which urges the roller 124 upwardly. When the adjustable pressure in the cylinder 121 is exceeded, a switch is operated to lower the roll speed of stand 101 or to increase the roll gap, thereby producing equilibrium in the flow of material. Following the assemblies 12 are strip guides 13, Fig. 9, positioned either between the last stands of the roughing train or between the stands of an intermediate train. Each guide incorporates rollers 132 and 134 which prevent the strip from buckling. If the strip forces the rollers 134 upwardly against the pressure of cylinders 136, the drive to the train of rolls is automatically switched off. In the finishing train loop lifters are positioned between the roll stands to produce a tensile force in the strip. The combintaion of roll force together with either compressive or tensile forces in the strip, maintain the strip width uniform during rolling.

Abstract: 1431177 Automatic control of temperature; automatic current regulation PLATT SACO LOWELL Ltd 19 June 1973 [6 July 1972] 31737/72 Heading G3R and G3X In the automatic temperature control of a roller (1) Fig. 1 (not shown) of a yarn heating apparatus, a resistance temperature sensor 6, is mounted in the roller and is connected via a slipring and brush assembly 4, 5, 8, 9, 12, 13 to a circuit 14, the input impedance of the circuit 14 being high compared with that of the slip-ring and brush assembly so that variations in the impedance of the latter has substantially no effect on a control signal from the circuit 14. The sensor 6 is supplied with constant magnitude direct current from a circuit 10 so that the voltage thereacross is proportional to the temperature sensed and is applied to the inputs of a 1:1 amplifier 16 via brushes 12, 13 and slip rings 4, 5. The input impedance of the amplifier circuit is sufficiently high relative to the contact resistance of the brushes 12, 13 that little or no current flows through these brushes and hence there is substantially no voltage drop across the brushes and rings. The voltage applied to the amplifier will therefore be substantially that across the sensor. An output signal X from the amplifier is dependent upon the temperature sensed and is applied to a controller (not shown) for comparison with a desired temperature value for the roller, to produce an error signal. The error signal is used to control the supply of A.C. to a stationary induction heating coil (12) (Fig.1) arranged within the rotating roller 1. Constant current circuit. A potential divider including C 1  R 1  applies a reference voltage to the base of T 1  which in turn applies a constant voltage to the emitter of T 2 . A current C 2  R 2  is arranged to increase the resistance between the base and collector of T 2  when increases in the resistance of the slip-ring/brush arrangement 4, 9 and 5, 8 occur. The increase in the base/collector resistance of T 2  reduces the bias on T 2  and reduces the collector current thereof passing through a 470K# resistor. Thus the voltage applied across the base/collector of T 2  will increase to compensate for brush contact. Resistance increase and constant current will be supplied to the sensor 6.

Filed: 1969-06-25
Abstract: 1278292 Spray carburetters BRITISH MOTOR CORP Ltd 25 June 1970 [25 June 1969] 31980/69 Heading F1B In a carburetter having a rotary air-choke valve 4, Fig. 1, and a fuel metering valve 11 conjointly controlled in accordance with the depression in passage 1 by a diaphragm 20 via a rack-and-pinion 9, 8 or via a flexible tape (30), Fig. 5 (not shown), the choke valve has an extensive cut-away portion which provides the variable choke passage 13. The cut-away portion is arch-shaped so that at idling it engenders a relatively large movement of the valve 11 for small variations in air-flow. The valve 4 is biased towards its closed position by a flat spiral torsion spring (23), Figs.2, 3 and 4 (not shown), which spring or its anchorage may be responsive to temperature to increase the closing torque of the spring when the incoming air temperature reduces. The valve 4 is supported at each side by ball bearings (5) carried by endplates (6) which can be moved relatively to housing 7 to reduce the working clearance between the housing and valve. Jet tube 15 is adjustable along its axis in accordance with fuel temperature by a bi-metallic strip (28) attached to the lower end thereof, for compensation of viscosity changes in the fuel due to temperature change thereof. The chamber 24 above the diaphragm 20 is communicated with atmosphere through an orifice 22 to produce a damping effect. This may be embraced by arranging on top of the diaphragm a needle valve member co-operating with the orifice. Alternatively, the chamber 24 may be filled with oil and an open-topped oil reservoir is then arranged immediately above the chamber 24 and communicating therewith through a needlecontrolled orifice.
